- 2 Claims.

This invention relates to a pan washing machine, and more particularlytosuch a machine adapted for the washing of pans utilized in cooking orthe like.

A primary object of the invention is the provision of an improved panwashing machine, including a plurality of rotary brushes, which brushesare doubly rotatable, both about their own axes and about acommon-central axis.

An additional object of the invention is the provision of such a devicewherein the relative position of the brushes may be varied toaccommodate a variety of sizes of pans.

A still further object of the inventionis the provision of means inassociation with such a device for supplying a cleaning fluid, such aswater or the like, to the pans during the washing and scouringoperation.

A further object of the invention is the provision of such a devicewhich will be sturdy and durable in construction, reliable and-efficientinoperation, and comparatively simple and inexpensive to manufacture andoperate.

Still other objects reside in the combinations of elements, arrangementsof parts, and features of construction, all as will be more fullypointed out hereinafter and disclosed in the accompanying drawings,wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a side elevational view of one form of device embodying thisinvention, certain concealed parts thereof being indicated in dottedlines,

Figure 2 is an end elevational view of the device of Figure 1 as viewedfrom the left,

Figure 3 is an end elevational view of the device shown in Figure 1 asviewed from the right,

Figure 4 is a sectional view taken substantially along the line l4 ofFigure 1, as viewed in the direction indicated by the arrows,

Figure 5 is a sectional view taken substantially along the line 5-5 ofFigure 3, as viewed in the direction indicated by the arrows, and

Figure 6 is a sectional view taken substantially along the line 6-6 ofFigure 4, as viewed in the direction indicated by the arrows, butshowing the outer plate in position.

Similar reference characters refer to similar parts throughout theseveral views of the drawmgs.

Having reference now to the drawings, there is generally indicated at H)a base plate, which carries a supporting member ll, having a, bearingmember l2 thereon, which supports an interme- 2 diate portion of arotatable hollow shaft l3. The extremity of the shaft I3 is journaledfor rotation in a bearing member l4, secured as by bolts IE, to

' a supporting plate I6, which is secured in any desired manner, as bywelding IT, to the base 10. The shaft [3 carries a gear 18, by means ofwhichit is adapted to be rotated, any suitable mechanism (not shown)being provided to accomplish such rotation. I

Suitably secured to the outer face of plate It, as by welding I9, is aring gear 20, provided, as best shown in Figure 4, with internal teeth 2I.

Secured to the shaft l3, as by akey 22, is a plate 23 adapted to berotated by rotation of he shaft. The outer extremity of the hollow shafti3 is closed, as by a threaded plug 24, and a plurality of tubes 25communicate with the interior of the shaft, and extend outwardly beyondthe plug 24, for a purpose to be more fully described hereinafter.

The plate 23 has positioned on the inner face thereofa plurality of stubaxles 26, as best shown in Figure 6, which axles carry rotatably mountedgears 21 adapted to engage the teeth 2| of the ring gear 20. The gears21, which are preferably of fiber or similar composition, are adapted tomesh with gears 28, which may be of metal or similar material, whichgears are keyed or otherwise suitably secured to shafts 29, which extendoutwardly through suitable arcuate slots 30 (see Figure 3) in plate 23.Locking nuts 3| surround each of the shafts 29, extending through theslots 30, and threadedly engage threaded apertures in the extremities oflinks 32, the opposite ends of which links encircle the axles 26.Brushes 33 of any desired type are adapted to be carried by the shaft29. Clamping plates 35 are positioned over the apertures 30, and betweenthe plate 23 and the locking nuts 3|, suitable apertures in the plate 35permitting the lower extremity of the 'nut to be passed therethrough.Guide pins 36 are provided adjacent the plate 35, to guide the path ofmovement thereof when the shafts 29 are moved in a manner and for apurpose to be more fully pointed out hereinafter.

As best shown in Figure 4, each of links 32 has pivotally secured, as bya pivot 31, to a mid point thereof, an additional link 38, the oppositeend of which is pivotally secured as by a pivot 39 to a point of atriangular member or plate 40 coaxially mounted with respect to thetubular member 13, for rotatable movement thereabout. Secured to one ofthe pivots 39 is an angled link M, at the opposite extremity of which isa handle member 3 42 which extends exteriorly of the plate 23 through anarcuate slot 43 (see Figure 3).

From the foregoing, the operation of the device should now be readilyunderstandable. In adjusting the device for a given size of pans, thelock nuts 3| are first loosened, permitting the shaft 29-to1movefreely-in the slot3ll. The handle 42 is thenmoved in-ladesireddirection, "which through the arm 4|, moves the triangular plate40, which, in turn, through the links 38 andi '32; varies the positionof the shaft 29 and their associated brushes within the limitsdefined-by the slots 30. Thus it will be seenthat a variety$of sizes ofpans may be utilized in: conjunctionwith the device, the brushes beingso placed as toz thoroughly scour the rims ofsuch, pans After thebrushes are set in the desired position,"'the lock nuts 3| aretightened, water or otherbsuitable cleansing fluid introduced throughthe hollow shaft 13, fromwhich it escapes through-v the tube 25-to theinterior surface of the pan, andthe shaft- I3 rotated relativelyrapidly. This rotation -will vcause the plate-23 to rotate, and hencethe brushes to-rotate about acommon -axis,v.-while simultaneouslythe'engagement ofthe gears'Z'I With the teeth 21 of ring gear 20 will,through the gears'28, occasion rotation of the shafts 29,

and hence their associated brushes each about its own individualaxis.

Thus it. will be seen, that there is herein'provided'an improvedcleaning device particularly adapted for use with circularfiobjects,such as cooking pans, or the like, which accomplishes all the objectsoi-this invention and others, including many advantages of greatpractical utility and commercial importance.

As many embodiments maybe "made OfithiS inventive concept, and as manymodifications may be made in the embodiment "hereinbefore shown anddescribed, it is to be understood that all matter herein is to beinterpreted merely as illustrative; and not in a'limiting "sense,

I claim:

1. In a pan-washing device, in combination, a hollow rotatable shaft, astationary ring gear surrounding said shaft, a plate rotatable by said 5shaft, driver gears mounted on said plate meshing with said ring gear,driven gears meshing Withvsaid driver gears; brushes' rotatable by said-;second=mentioned gears, tubes extending from said shaft adjacent saidbrushes for introducing mashing fluid to a pan, and means for varyingthe relative position of said rotatable brushes with respect to saidring gear, said last mentioned 5 11183118 comprisingran apertured platepositioned onv-saidkshaft, :means including links coupling 15. pairs of.driven. and driver gears for rocking move- ,ment, and rods.v connectingsaid apertured plate and' said links.
